Value range for RT rotation

Description
Calling frame
By specifying the system variable $P_UIFRNUM you can access the current zero offset set
with $P_UIFR or G54, G55, ...
($P_UIFRNUM contains the number of the currently set frame).
All other stored settable $P_UIFR frames are called up by specifying the appropriate number
$P_UIFR[n].
For predefined frame variables and user-defined frames, specify the name, e.g.,
$P_IFRAME.
Calling data
The axis name and the frame component of the value you want to access or modify are
written in square brackets, e.g., [X, RT] or [Z, MI].

5.2 Frame variables / assigning values to frames
Assign the angle of rotation RT around the X axis
from the currently valid settable zero offset
$P_UIFRNUM to the variable R10.
Assign the offset value TR in Z from the data
record of set frame no. 25 to the variable R12.
Assign the offset value TR in Y of the current
programmable frame to the variable R15.
Modify the offset value TR in X of the current
programmable frame. X25 applies immediately.
This command automatically establishes the reference to the
currently valid settable zero offset.
Specify the frame number n to access the settable frame no.
n.
Specify the component to be read or modified:
TR Translation
FI Translation Fine
RT Rotation
SC Scale scale modification
MI Mirroring
The corresponding axis X, Y, Z is also specified (see
examples).
